Delete rows in spreadsheet that are not needed.

I am trying to write a program in VBA that grabs a spreadsheet from my computers desktop, opens the spreadsheet, looks at a particular column and loops through the spreadsheet (just looking at this one column throughout the spreadsheet) looking for the following words ('Data Due', 'Files Due', Indent Due', 'Quantities Due').

The program loops through the spreadsheet looking at this one column and if the cell doesnt contain any of these words, the entire row gets deleted.

It then loops through this column until the end of the file is reached.
